Dynamical systems analysis of tachyon dark energy model from a new perspective

Understand

In this work we present a new scheme to study the tachyon dark energy model using dynamical systems analysis by considering parametrization of the equation of state(EoS) of the dark energy.

• Both the canonical and phantom field dynamics are investigated.
• In our method we do not require any explicit form of the tachyon potential.
• Instead of the potential we start with an approximate form of the EoS of the tachyon field.
